kanelp Posted February 17, 2012 Share Posted February 17, 2012 (edited) Can you choose the type of Alpha channel that Paint.NET saves? Premultiplied or non-premultiplied/straight? Otherwise, what is the type of alpha channel that Paint.NET saves by default? Kane Edited February 17, 2012 by kanelp Quote Link to comment Share on other sites More sharing options...
Ego Eram Reputo Posted February 17, 2012 Share Posted February 17, 2012 Paint.NET saves the alpha channel in the same way as the RGB channels. One byte per pixel, which gives you 256 values ranging from 0 (fully transparent) to 255 (fully opaque). As far as I know there is no option to save a modified alpha channel (unless it's in one of the file formats I don't habitually use).

I.e. the standard .png filetype uses unassociated alpha and the optipng plugin allows to pre-multiply the RGB values. Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted February 17, 2012 Share Posted February 17, 2012 By default everything is "straight" alpha, unless explicitly stated otherwise.
